It was another week of stellar (and not so stellar) fashion. On a night celebrating her Billboard Music Woman of the Year Award, Ariana Grande, stepped out looking quintessentially Ariana Grande, complete with cute strapless dress, thigh-high boots, and signature updo. The week also saw some fiercely understated, glamorous looks courtesy of Natalie Portman, Mandy Moore, and Naomie Harris. Maye Musk was a masterclass in co-ordinating contrasting separates, whilst Margot Robbie and Saoirse Ronan dressed in gowns fit for queens. But don’t you worry, there was plenty to question, like Janelle Monae‘s bizarre almost assless chaps. Intrigued? Read on, for this week’s style winners and losers.

Ellie Goulding

Ummm…. who thought a soft, silky pink gown paired with Kermit the frog-coloured, Barbie-esque neon green heels was a good idea? It’s a total clash of looks, and sadly for Ellie, ruins what would have been a perfectly acceptable red carpet outfit.

Janelle Monae

Ok, we’ll be honest, we're fine with the exaggerated shoulders and slit sleeves. It's the ass-lite chaps of this pinstripe grey pantsuit that we can't get on board with. Ditch the weird crotch area and this would be a winner. As is, however, it is not.

Jennifer Aniston

Black? Simply cut? Mini-length? So far, so Jennifer. It’s fairly standard Aniston attire at this point, so we’re not surprised, but it’s more than a little dull. There’s some shine to this particular dress, but, it’ll need more than that to go from loser to winner.

John Legend

Trust John to keep things fresh. He’s hitting all the right fashion notes in this teal two-piece, reminding us menswear has plenty of room for experimentation.

Natalie Portman

On paper, this is fairly unremarkable, but in this satin black two-piece, Natalie shows she can new breathe life into an old look with understated glam. The lack of jewellery and layers beneath the blazer keep attention on the suit’s clean lines, whilst the deep red lip and well-defined eyes bring some welcome drama.

Margot Robbie

Well, that one’s way to show the world you are literally playing a queen in your latest movie. On her way to said film’s premiere, Margot glitters in this unusual gown. The overlay of the longer sheer layer over the shorter halter-neck is fantastic, bringing a modern feel to an otherwise decidedly regal look.

Saoirse Ronan

Also out to remind us of her regal status was Saoirse, looking all dramatic in this extraordinary dress. As if the shoulder ruffles weren’t enough of a showpiece, there’s an actual heart embellishment on her hip. Throw in printed French text (‘dress for the Cote d’Azur in winter’), and this is a look to remember.

Mandy Moore

Mandy almost continued her long fashion winning streak in this navy number. The colour flatters, the hair is neat and bouncy, and the deep pink lip is point. One quibble? The length of the dress, which brings the entire look down. Next time, Mandy.

Naomie Harris

Naomie is a knockout in this plunging printed dress. The smattering of purples, pinks and oranges work together beautifully, and the embellishment at the waist, along with the muted gold earrings and ring tie it all together.

Olivia Wilde

Proving you can wear a pantsuit and still look scruffy however, is Olivia in fire-engine red. It’s in need of an iron, and maybe more than a matching bra as a full layer. The pants are also too long for her, shrouding her shoes entirely.

Maye Musk

How is it the dazzling gold jumpsuit isn’t even the most remarkable part of Maye’s outfit? Pairing it with a red leather beret, the dangliest of earrings, and a cobalt blue velvet blazer is. She’s got some serious style flair, we’ll give her that. It’s bold, unapologetic, and awesome.

Miley Cyrus

There’s not a lot to love in Miley’s latest fashion ensemble. From those distracting hair baubles, her too-tight up do, cheap-looking PVC-jumpsuit, and those stilted boots, she’s scoring zero fashion points with us. An unintentional reminder that more is not always more.
